A pamwamba kuthamanga mlatho cranendi imodzi mwa mitundu yodziwika bwino komanso yosunthika ya zida zonyamulira pamwamba. Nthawi zambiri amatchedwa crane ya EOT (Electric Overhead Traveling crane), imakhala ndi njanji yokhazikika kapena njanji yomwe imayikidwa pamwamba pa mtengo uliwonse wanjanji. Magalimoto omalizira amayenda motsatira njanji zimenezi, akunyamula mlathowo ndikukwera bwino m’mbali yonse ya malo ogwirira ntchitowo. Chifukwa cha kapangidwe kameneka, crane yapamwamba yoyendetsa mlatho imakhala yothandiza kwambiri m'malo omwe katundu wolemetsa amafunika kusamutsidwa mosamala komanso pafupipafupi.
Chimodzi mwazabwino zamakina othamanga kwambiri ndikutha kutengera mapangidwe a girder single ndi double girder bridge. Mlatho umodzi wa girder nthawi zambiri umagwiritsa ntchito trolley yokhomeredwa pansi ndi kukweza, pomwe mlatho wapawiri nthawi zambiri umagwiritsa ntchito trolley ndi kukwera pamwamba. Kusinthasintha uku kumathandizira mainjiniya kusintha makina a crane kuti agwirizane ndi zosowa zosiyanasiyana zonyamula. Mwachitsanzo, crane yam'mwamba ya monorail ingakhale yoyenera kuyenda pamzere wokhazikika, koma zikafunika kusinthasintha komanso kukweza kwakukulu, crane ya EOT pamasinthidwe othamanga apamwamba imapereka zabwino zambiri.
Mosiyana ndi ma cranes othamanga,pamwamba kuthamanga mlatho cranesalibe malire pa mphamvu. Atha kupangidwa kuti azigwira zolemetsa kuyambira pa pulogalamu yaying'ono ya 1/4-tani mpaka matani opitilira 100. Chifukwa amakwera njanji yomwe ili pamwamba pa mtengo wanjanjiyo, amatha kuthandizira mipata yotakata ndikukweza mtunda wautali. Kwa nyumba zomwe zili ndi zipinda zopanda malire, izi ndizofunikira kwambiri. Mapangidwe apamwamba a mlatho wa girder awiri amalola kuti chokwera ndi trolley kuthamanga pamwamba pa zomangira, kuwonjezera 3 mpaka 6 mapazi a kutalika kwa mbedza. Izi zimakulitsa kutalika kokwezeka komwe kulipo, chinthu chomwe crane yam'mwamba ya monorail sichingapereke.
A pamwamba kuthamanga mlatho cranendiyoyenera malo ochitirako misonkhano, malo osungiramo zinthu, ndi malo olemera a mafakitale komwe nthawi yayitali komanso mphamvu zambiri zimafunikira. Zonyamula zikadutsa matani 20, makina othamanga kwambiri amakhala abwino kwambiri. Mothandizidwa ndi zitsulo zomangidwa ndi nyumbayo kapena mizati yothandizira paokha, ma cranes awa amapangidwira kuti azigwira ntchito zolemetsa. Mosiyana ndi izi, pamene zofunikira zokweza zimakhala zopepuka, monga matani 20 kapena kuchepera, crane yothamanga kapena monorail imatha kuganiziridwa kuti ikhale yosinthika kwambiri.
Ubwino winanso waukulu wamakina othamanga kwambiri ndikuti amachotsa chinthu choyimitsidwa chomwe chimapezeka pansi pa cranes. Chifukwa crane imathandizidwa kuchokera pamwamba, kukhazikitsa kumakhala kosavuta komanso kukonza kwamtsogolo kumakhala kosavuta. Kuyang'anira ntchito, monga kuwunika momwe njanji imayendera kapena kutsatira, kumatha kumalizidwa mwachangu ndi nthawi yochepa. Pa moyo wake wogwira ntchito, crane ya EOT pamapangidwe apamwamba kwambiri imapereka kukhazikika komanso kuchita bwino poyerekeza ndi makina ena a crane.
Ngakhale kuti makina othamanga kwambiri amafunika kuyang'anitsitsa nthawi ndi nthawi njanji kapena njanji, njirayi ndi yowongoka komanso imatenga nthawi yochepa kusiyana ndi mitundu ina ya crane. Mapangidwe amphamvu amatsimikizira moyo wautali wautumiki ngakhale mukugwira ntchito mosalekeza. Makampani ambiri amasankha pamwamba akuthamanga mlatho Kireni osati chifukwa cha mphamvu zake mkulu komanso kudalirika ake kutsimikiziridwa ndi chomasuka ntchito. Momwemonso, malo omwe amayamba kutengera chowongolera chapamtunda cha monorail kuti anyamule mopepuka nthawi zambiri amakula kukhala makina amtundu wa EOT pomwe zosowa zawo zogwirira ntchito zikukula.
Mwachidule, apamwamba kuthamanga mlatho cranendiye njira yabwino kwambiri yokwezera mafakitole omwe amafunikira kuchuluka kwakukulu, kutalika kwautali, komanso kutalika kokweza kwambiri. Ndi masanjidwe omwe akupezeka muzopanga zonse ziwiri za girder ndi girder, komanso zokweza kuyambira ma kilogalamu mazana angapo mpaka matani opitilira 100, crane yamtundu uwu wa EOT imapereka mphamvu, kukhazikika, komanso mtengo wanthawi yayitali. Kwa ntchito zomwe kusinthasintha ndi katundu wopepuka ndizofunika kwambiri, crane ya pamwamba pa monorail ikhoza kukhala yoyenera, koma kukweza kwakukulu komanso kuchita bwino kwambiri, makina othamanga kwambiri amakhalabe chisankho chomwe amakonda.
